Change RDLC window to UserControl

Question

Hello, the moment I click on the "Business Listing" button, it displays a window of my report with relevant information. I am trying to show it in my ShellView instead of "windows pop up."

Old code

PreviewForm.xaml

<Window .......
    <Grid> 
         <WindowsFormsHost Name="MyHost" Margin="0,0,0,0" Visibility="Visible">
             <rv:ReportViewer x:Name="_reportViewer" ForeColor="AliceBlue" Visible="True" Dock="Fill"/>
        </WindowsFormsHost>
    </Grid>
</Window>

PreviewForm.xaml.cs

public string reportSource { get; set; }
public Microsoft.Reporting.WinForms.ReportDataSource reportDataSource { get; set; }

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    try
    {
        this._reportViewer.Reset();
        this._reportViewer.LocalReport.ReportEmbeddedResource = this.reportSource;
        this._reportViewer.LocalReport.DataSources.Clear();
        this._reportViewer.LocalReport.DataSources.Add(this.reportDataSource);
        this._reportViewer.LocalReport.Refresh();
        this._reportViewer.RefreshReport();
    }
    catch (Exception Ex)
    {
        Ex.ToString();
    }
}

ReportViewModel

public void BusinessListing()
{
    try
    {
        BindableCollection<BusinessDTO> Firms;
        using (var ctx = DB.Get())
        {
            Firms = new BindableCollection<BusinessDTO>(BusinessDTO.ReportBusiness(ctx));
        }

        Microsoft.Reporting.WinForms.ReportDataSource reportDataSource1 = new            Microsoft.Reporting.WinForms.ReportDataSource();
        reportDataSource1.Name            = "BusinessDTO";
        reportDataSource1.Value           = Firms;
        Reports.ReportPreviewForm preview = new Reports.ReportPreviewForm();
        preview.reportDataSource          = reportDataSource1;
        preview.reportSource              = "Reports.ListingReports.BusinessListingReport.rdlc";
        preview.Show();
    }
    catch (Exception Ex)
    {
        MessageBox.Show(Ex.Message);
    }
}

ReportGridView

<shell:GridScreenControl.Grid>
    <Grid >
        <panes:ReportPreviewForm/>
    <Grid >
</shell:GridScreenControl.Grid>

Additions.

I converted the PreviewForm to UserControl.

Changed Window_Loaded=>

public void Update()

and in my ReportViewModel instead preview.Show()I have preview.Update() It currently just shows a blank white screen.
